8-(3-Chlorostyryl)caffeine, also known as 3-chloro-8-styrylcaffeine or 3-CSC, compound shares a structural resemblance with caffeine. While the exact mechanism of action of 8-(3-Chlorostyryl)caffeine remains partially elusive, it is believed to function as an antagonist of the A2A receptor. By doing so, it obstructs the binding of adenosine to the receptor, thereby impeding downstream signaling pathways activation. Additionally, 8-(3-Chlorostyryl)caffeine displays the ability to inhibit the enzyme cyclooxygenase-2 (COX-2).
